Yes! You will get in BIG trouble if you list your counterfeit PS3 controllers on eBay. Counterfeits/ copies/ fakes/ bootlegs are NOT allowed on eBay, please read their policies addressing that:

Also, we have stressed in several posts (on forum) to stay away from any products that are offered as branded by any Chinese supplier as the likelihood of these being fake is 9 out of 10. In fact we had mentioned it in our description for DH Gate as a warning:
Important Note: Please be aware that a lot of sellers use this marketplace to sell counterfeit goods and we do not recommend purchasing ANY branded goods off this site as there is a 99% chance they will be fake.
DH gate is a great source for most items except brand name products.
You can try selling those in other venues will garage sales or flea markets but I doubt you can sell those online and get away with them being fakes.
Good luck! :)
